By the time the translation was made (~1920), it could also be "know-it-all" (I assume this started as a sarcastic use of its sense of "headmaster") which is pretty close to its typical meaning today—to me it implies someone who often, unnecessarily or inappropriately, corrects others, but that may be a recent connotation, and it's still close. We'd have to find the original text and consult a translation dictionary, I expect, to figure out exactly which sense was intended.
